Question

Write the equation through the points (0,9) and (5,13)

Answer 1

Answer:

4x-5y+45=0.

Step-by-step explanation:

1) formula is:

$\frac{x-X_A}{X_B-X_A} =\frac{y-Y_A}{Y_B-Y_A};$

2) if point A is (0;9) and point B is (5;13), then:

$\frac{x}{5} =\frac{y-9}{13-9}; \ => \frac{x}{5} =\frac{y-9}{4}; \ => \ 4x-5y+45=0.$
